10. What is T price, C price, MTM P/L
T price is the price at which a stock was originally purchased.
C Price is the current last price that the stock was traded at.
MTM P/L is the calculation of the profit or loss an investor makes when holding shares and compares the original purchase price with the current (marked-to-market) price multiplied by the number of shares held. So the MTM P/L equals the C price less the T price multiplied by the number of shares held.
